Broadband Modem Mixed-signal Front End - Analog Devices

The AD9868 is a Mixed-Signal front-end (MxFE) IC for
transceiver applications requiring Tx path and Rx path
functionality with data rates up to 80 MSPS. A lower cost, pin-
compatible version of the AD9865 the AD9868 removes the
current Amplifier (IAMP) IOUTP functionality and limits the
PLLVCO operating range of 80 MHz to 200 MHz.
The part is well-suited for half- and full-duplex applications.
The digital Interface is extremely flexible, allowing simple
interfacing to digital back ends that support half- or full-duplex
data transfers, often allowing the AD9868 to replace DiscreteADC and DAC solutions. Power-saving modes include the
ability to reduce power consumption of individual functional
blocks or power down unused blocks in half-duplex applications.
A serial port Interface (SPI) allows software programming of
the various functional blocks. An on-chip PLLClock multiplier
and synthesizer provide all the required internal Clocks as well
as two external Clocks from a single crystal or Clock source. By Analog Devices, Inc.
